When to prune aglaonema pictum bicolor in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune aglaonema pictum bicolor

Aglaonema pictum Bicolor is a collector's plant grown primarily for its striking camouflage foliage. It needs very little pruning — remove dead or damaged leaves at the base as they appear. The plant grows slowly and naturally maintains an attractive form without any corrective cutting.

Why is UK pruning timing different from American advice?
Most pruning guides online are written for US conditions and anchored to USDA zones. Britain's maritime climate gives milder winters but later, less predictable last frosts — from March in the south-west to mid-May in the north — so the RHS advises against winter pruning for most plants: it pushes out soft growth that a late frost then kills. Britain also has the nesting-bird law, which has no US equivalent.
